The synthesis of a tricyclic guanidine as a model compound for ptilomycalin A and related guanidine alkaloids is described. The synthesis starts from succinimide and features an N -acyliminium ion coupling, an Eschenmoser sulfide-contraction and an N

The syntheses of three bicyclic guanidines as model compounds for the guanidine alkaloid ptilomycalin A are described. The guanidines are prepared from pyrrolidin-2-one via an N-acyliminium ion coupling reaction with silyl enol ethers and a direct gu

Highly stereoselective N -acyliminium ion coupling reactions of β-ketoester derived silyl enol ethers with enantiopure lactams derived from ( S )-malic acid are reported. This reaction type is applied in the synthesis of the enantiopure C-2 substitu

Highly stereoselective syntheses of enantiomerically pure γ-amino acids statine and 4- epi -statine from ( S )-malic acid are described by using, respectively, an intramolecular α-acylamino radical reaction and an intermolecular N -acyliminium ally
